Does R have function startswith or endswith like python?

    > startsWith('abc', 'a')
    [1] TRUE
    > startsWith('abc', 'c')
    [1] FALSE

    > endsWith('abc', 'a')
    [1] FALSE  
    > endsWith('abc', 'c')
    [1] TRUE

As added to base in 3.3.0, startsWith (and endsWith) are exactly this.

    > startsWith("what", "wha")
    [1] TRUE
    > startsWith("what", "ha")
    [1] FALSE
